科学家称：远古时代男主内女主外

Scientists may finally have confirmed what every woman has always suspected. Even back in prehistoric times, the female of the species was very much the boss. A study has found evidence of "alpha cavewomen" roaming the plains and calling the shots while the menfolk slobbed at home。

Alpha cavewoman appears to have travelled far wider than her male counterpart, the research showed. She might even have been the one who went out clubbing, so to speak – reversing the popular conception that it was the bloke who bashed the girl on the head and dragged her home by the hair。

But something seems to have happened to the evolution of the species after those times between 1.7million and 2.4million years ago. A couple More millennia would have to pass before female independence re-emerged with the liberation of the Swinging Sixties。

The findings, detailed in the journal Nature, were made by Oxford University researchers and an international team of scientists. Using lasers and advanced technology, they analyzed enamel from fossilized teeth found in cave systems in South Africa。

Oxford professor Julia Lee-Thorp said the difference between males and females was "completely unexpected"。

Her team measured the strontium isotope ratios in canine and third molar teeth in 11 Paranthropus individuals from the Swartkrans cave, as well as in teeth from eight Australopithecus africanus individuals from the nearby Sterkfontein cave. The researchers also measured the strontium in 170 plants and animals currently living near the caves to get a sense of the different strontium signatures of the region。

Analysis of their teeth showed whether or not individuals were local or had arrived from another area. More than half the female teeth were from outside the region, compared to about 10 percent of the male teeth, the international team of researchers found。

The experts concluded that most males lived and died in their birthplaces, while females were more likely to find new homes。

Modern humans, who are influenced by relatively recent cultural practices such as marriage and property ownership, are difficult to compare to our early ancestors, a professor added。科学家称：远古时代男主内女主外

而一位教授补充说，现代人类因为受到婚姻以及财产等近代文化内涵的束缚，已很难像我们祖先那样生活。

科学家终于确认了每个女人都曾怀疑的事情。那就是，早在史前时代，女性就是“大老板”了。一项研究发现了“阿尔法穴居女性”的存在证据，证明了远古时期女性在外纵横捭阖，而男性只是“窝”在家里。

研究发现，“阿尔法穴居女性”似乎比同时代男性跋涉范围更广。她甚至还有可能外出聚会，可以说颠覆了传统认知：女子一旦出门，男子就要对其劈头盖脸一顿打，最后扯着她的头发拉回家。

但是这样的日子只是从240万年前持续到170万年前，在人类接下来的进化过程中一些事情发生了。至“摇摆六十年代”解放运动以及随之而来再次出现的女性独立潮，成千上万年转瞬即逝。

详尽的研究结果刊载于《自然》杂志。研究由牛津大学研究人员和跨国科学家团队联合执行。通过激光和先进技术，他们分析了南非几处穴居内古人类牙齿化石的珐琅质。

牛津大学教授茱莉亚称男性和女性的分析结果差异“完全出乎意料”。

她的团队计算了瓦特克朗洞穴内11个巴兰猿人、 斯托克方丹洞穴附近出土的8个非洲南猿的犬齿和第三臼齿的锶同位素比值。研究人员还测量了现居住在上述洞穴附近的170种植物和动物的锶含量，以获取该地区不同水平的锶特征。

牙齿分析可显示主人是否为本地人，是否来自其他地区。而跨国研究小组发现，超过一半的女性牙齿主人来自其他地区，而来自地区的男性牙齿主人只占10%。

专家故而得出结论，大部分男性生老病死于出生地，而女性更有可能迁往新居。
